BACKGROUND Field of the Disclosure

The disclosure generally relates to containers for aircraft emergency equipment and to methods of changing aircraft emergency equipment, and more specifically to containers for aircraft emergency escape slides and methods of changing aircraft emergency escape slides.

Related Technology

Modern passenger aircraft require quick egress options in case of emergency. Because many modern passenger aircraft have entry doors that are ten feet or more above ground level, passengers need some sort of device to allow them to get to the ground safely. Inflatable emergency escape slides have been used for this purpose. The emergency escape slide is usually made from an inflatable flexible material. When not inflated, the emergency escape slide is folded up into a small volume and stored in or near the egress door. When needed, the emergency escape slide is filled with a gas so that it inflates to a semi-rigid slide structure that extends from the egress door to the ground. While this solution to speedy egress of a passenger aircraft has generally been very successful, the emergency escape slides require periodic checking, maintenance, and/or replacement to ensure that the emergency escape slides will operate correctly in the case of an emergency.

In large passenger aircraft (in particular in wide-body, long range aircraft), these emergency escape slides can weigh 100 to 150 lbs (45-68 kg) or more. Moreover, these large passenger aircraft can have eight or more emergency escape slides. In order to change or maintain these emergency escape slides, maintenance personnel must carry a folded slide into the aircraft through the egress door. After entering the aircraft, the folded slide must be carried down an aircraft aisle to the correct egress door. Once position by the correct egress door, maintenance personnel must remove the old slide and then lift and position the new slide in the correct location. Often during transport of the new slide to the correct egress location, the new egress slide can become hooked or torn on various aircraft parts, which would require a new slide to be obtained. Additionally, due to the weight of the slides, maintenance personnel are often injured during the transfer process by bending over to pick up the slide off of the ground.

Additionally transportation and storage of the slides when not installed in an aircraft can be a problem. Typically, the slides are stored in a wooden container that is liftable by a forklift. These wooden containers are very heavy and not very durable. Furthermore, lifting the slide out of the wooden container requires maintenance personnel to bend over, which subjects the maintenance personnel to the possibility of back or other injuries. These injuries result in a loss of workdays and a loss of efficiency, which can be a problem for the employer.

DETAILED DESCRIPTION

The emergency escape slide containers described herein advantageously allow an inflatable emergency escape slide to be stored and transported in a single container from a storage facility to an emergency escape slide storage location on aircraft. These emergency escape slide containers facilitate movement of the emergency escape slide by forklift or other transportation device from a storage location in a storage facility to an aircraft and then to a predetermined location in an aircraft. The emergency escape slide containers are robust and yet lightweight so that they are easily maneuverable within an aircraft by one or two maintenance personnel. Moreover, the emergency escape slide containers are sized to accommodate deflated and folded emergency escape slide in one portion and another deflated and folded emergency escape slide in another portion so that the container itself can be used to remove an existing emergency escape slide and to install a replacement emergency escape slide on an aircraft. The emergency escape slide containers also reduce on-the-job injuries because the emergency escape slide does not need to be removed from the container before transporting the emergency escape slide within an aircraft.

Turning now to FIGS. 1-6, one embodiment of an emergency escape slide storage container 10 is illustrated. The emergency escape slide storage container 10 includes a first or upper portion 12 and a second or lower portion 14 removably attached to one another. Generally speaking, the first portion 12 and the second portion 14 combine to store a deflated emergency escape slide therebetween. The first portion 12 and the second portion 14 protect the emergency escape slide during storage and transportation. Moreover, the first portion 12 and the second portion 14 may be separated from one another so that the emergency escape slide remains attached to one of the first portion 12 and the second portion 14. The portion of the container to which the emergency escape slide remains attached is light enough and maneuverable enough to be transported down and aisle of the passenger aircraft by one or two maintenance personnel. In some embodiments, the first portion 12 and the second portion 14 may be identical to one another. In other embodiments, the first portion 12 and the second portion 14 may have slight differences as long as the first portion 12 and the second portion 14 are removably attachable to one another and that either the first portion 12 or the second portion 14 may be transported down an aisle of an aircraft with an emergency escape slide.

The first portion 12 may include a first end wall 16 and a first sidewall 18. Similarly, the second portion 14 may include a second end wall 116 and a second sidewall 118. The first end wall 16 and the first sidewall 18 define a first storage space 20 (FIG. 5). Similarly, the second end wall 116 and the second sidewall 118 form a second storage space 120 (FIG. 3). The first portion 12 and the second portion 14 together form a third storage space 320 that is equal to a combination of the first storage space 20 and the second storage space 120. The first storage space 20 is sized and shaped to receive an emergency escape slide such as an existing emergency escape slide 201 that was previously contained in an emergency escape slide storage location 204 on an aircraft 202 (see FIGS. 8-10). Similarly, the second storage space 120 is sized and shaped to receive an emergency escape slide such as a replacement emergency escape slide 200 to be stored in the emergency escape slide storage location 204 on the aircraft 202. In the embodiment illustrated in FIGS. 1-6, the first sidewall 18 may include a plurality of sidewall portions 18 a, 18 b 18 c, 18 d that form a rectangular shape. In other embodiments, the sidewall 18 may include more or fewer sidewall portions that define other shapes such as circles, ovals, squares, polygons, or any other regular or irregular shapes, as long as the storage space defined by such shapes is capable of receiving an emergency escape slide.

A first restraining mechanism 22, such as belt, may be disposed within the first storage space 20. In some embodiments a second restraining mechanism 23 may also be disposed in the first storage space 20. In other embodiments, the first restraining mechanism 22 and/or the second restraining mechanism 23 may include other types of restraining devices, such as, strings, ropes, hook and loop fasteners, doors, clasps, clamps, or any other device that may be used to removably secure an emergency escape slide within the first storage space 20. The first restraining mechanism 22 may also include a plurality of restraining devices, such as a plurality of belts or a plurality of strings or ropes. When disposed in the first storage space 20, the emergency escape slide is releasably secured to the first portion 12 with at least the first restraining mechanism 22 and/or with the second restraining mechanism 23, so that the first portion 12 may be rotated lifted or otherwise oriented in any position and the emergency escape slide will not fall out of the first storage space 20.

An outer surface of the first sidewall 18 may include a first rolling mechanism 24 (FIG. 1). The first rolling mechanism 24 may include one or more ball rollers 26, such as omni rollers, that allow the first portion 12 to roll in any direction on a surface, such as an aircraft floor. The first rolling mechanism 24 may also include a unidirectional roller, such as a cylindrical nylon roller 28. By orienting the first portion 12 so that the first rolling mechanism 24 contacts the surface, the first portion 12 may be easily rolled along the surface by one or more maintenance personnel without having to lift the first portion 12 off of the surface.

The first portion 12 may also include one or more handles 30 to enhance the maneuverability of the first portion 12. The first portion 12 may further include one or more locking mechanisms 32, such as locking clasps or latches, that are capable of releasably securing the first portion 12 to the second portion 14. Similarly, the second portion 14 may include one or more handles 130 and/or one or more locking mechanisms 132.

A skid 34 may be removably attached to an outer surface of the first end wall 16 or to an outer surface of the second end wall 116. The skid 34 may extend outwards away from the outer surface of the first end wall 16 or the second end wall 116 so that the first portion 12 or the second portion 14 is elevated above a surface, such as an aircraft floor, when the skid 34 is resting on the surface.

The outer surface of the first end wall 16 or the outer surface of the second end wall 116 may also include a first recessed groove 36, 136, and a second recessed groove 38, 138, that are separated by a raised ridge 40, 140. The first recessed groove 36, 136 and the second recessed groove 38, 138 may be sized and shaped to receive a first fork of a forklift and a second fork of a forklift, respectively. The skid 34 and the recessed grooves 36, 136, 38, 138 combine to allow a forklift to lift the container 10 off of the surface when the container 10 is resting on the surface, such as when the container 10 is resting on the ground in a storage facility or on top of another container. As a result, the container 10 may be easily transported from the storage facility to a passenger aircraft by transportation device such as a forklift. The recessed grooves 36, 136, 38, 138 may be oriented generally perpendicular to a longitudinal axis A and generally parallel to a lateral axis B so that the recessed grooves 36, 136, 38, 138 traverse the container 10 in a generally widthwise manner. In other embodiments, the recessed grooves 36, 136, 38, 138 may traverse the container in a generally lengthwise manner.

The outer surface of the end wall 16, 116 may also include one or more recessed landings 42 that are sized and shaped to receive a portion of the skid 34. The recessed landings 42 locate and stabilize the skid 34 on the end wall 16, 116. The skid 34 may be removably attached to the end wall 16, 116 with a plurality of removable fasteners 44, such as thumbscrews, wing nuts, screws, clasps, latches, or any other removable fastener. The removable fasteners 44 may be secured to the skid 34 with a lanyard 45, or other securing device, so that the fasteners 44 do not become lost.

A distal portion 46 of the sidewall 18, 118 (i.e., distal to the end wall 16, 116) may include a plurality of tongues 48 and a plurality of grooves 50 (FIG. 5). The plurality of tongues 48 and the plurality of grooves 50 interact with corresponding tongues and grooves on the second portion 14 two locate and stabilize the first portion 12 on the second portion 14, or vice versa. Furthermore, the plurality of tongues and grooves on the first portion interact with the plurality of tongues and grooves on the second portion to locate the first rolling mechanism 24 on an opposite side of the container 10 from the second rolling mechanism 124.

Hereinafter, and with reference to FIGS. 7-11, a method of replacing an emergency escape slide on aircraft will be described. Initially, the replacement emergency escape slide 200 may be stored in one of the containers 10 described above. The container 10 may be housed in a storage facility. The container 10 may be transported from the storage facility to the passenger aircraft with a forklift or other transportation device. In particular, the forklift may approach the container 10, and orient forks generally parallel to the recessed grooves 36, 136, 38, 138. Because the container 10 is elevated off of the ground or off of a lower container 10 the forks of the forklift easily slide into the recessed grooves 36, 38. The forklift may then lift the container 10 off of the ground or off of another container 10. The forklift may then carry the container 10 to the passenger aircraft. Once the forklift is arrived at the passenger aircraft, the container 10 may be lowered to the ground and the forks of the forklift may be removed from the recessed grooves 36, 136, 38, 138. Once located on the ground, maintenance personnel may remove the first portion 12 from the second portion 14 (see FIG. 8), while the replacement emergency escape slide 200 (used to replace the existing emergency escape slide 201 stored in the emergency escape slide storage location 204) remains attached to the second portion 14.

As illustrated in FIGS. 7 and 8, the first portion 12 (as well as the second portion 14) may be rotated so that the first rolling mechanism 24 is oriented downwardly, towards a floor 203 of the aircraft cabin. Once resting on the first rolling mechanism 24, maintenance personnel may roll the first portion 12 on the floor 203 of the aircraft cabin, and down an aisle of the aircraft if needed, until the first portion 12 arrives in a predetermined location “L” proximate an emergency escape slide storage location 204. In the illustrated example, the predetermined location L is to a side of the emergency escape slide storage location 204. In some aircraft and as illustrated in FIGS. 7-11, the emergency escape slide storage location 204 is attached to (or otherwise proximate or adjacent to) an egress door 206 and itself includes a door that opens to allow access to the emergency escape slide (i.e., the existing emergency escape slide 201). As shown in FIG. 9, The first portion 12 may be oriented so that the first storage space 20 faces the emergency escape slide storage location 204. With reference to FIG. 10, the existing emergency escape slide 201 disposed within the emergency escape slide storage location 204 may then be released from the emergency escape slide storage location 204 and moved into the first storage space 20 of the first portion 12. Once located in the first storage space 20 the existing emergency escape slide 201 may be disposed and secured within the first storage space 20 of the first portion 12 by the first securing mechanism 22 and/or by the second securing mechanism 23. After the existing emergency escape slide 201 is secured within the first storage space 20, and as illustrated in FIG. 10, the first portion 12 may be reoriented so that the first rolling mechanism 24 is again resting on the floor of the aircraft cabin, and maintenance personnel may then roll the first portion 12 with the existing emergency escape slide 201 to a door of the aircraft 202 where the first portion 12 and the existing emergency escape slide 201 may be then removed from the aircraft 202.

Once the existing emergency escape slide 201 is removed from the aircraft 202, as illustrated in FIG. 10, the second portion 14, which contains the replacement emergency escape slide 200 secured in the second storage space 120, may be moved through the aircraft door and the aircraft cabin. Once located in the aircraft cabin, the second portion 14 may be oriented so that the second rolling mechanism 124 is located on the floor 203 of the aircraft cabin. The second portion 14 may then easily be rolled along the floor of the aircraft cabin, and down an aisle of the aircraft if needed, until the second portion 14 arrives in a predetermined location proximate the emergency escape slide storage location.

Once arriving at the predetermined location L proximate the emergency escape slide storage location 204, the second portion 14 may be oriented so that the second storage space 120 faces the (now empty) emergency escape slide storage location 204. Thereafter, the replacement emergency escape slide 200 may be released from the second portion 14 and moved into the emergency escape slide storage location 204. Once the replacement emergency escape slide 200 is secured in the emergency escape slide storage location 204, as illustrated in FIG. 11, the second portion 14 may be oriented so that the second rolling mechanism 124 is located proximate the floor the cabin. The second portion 14 may then be rolled along the cabin floor to an exit of the aircraft 202. After removing the second portion 14 from the aircraft 202, the second portion 14 may be joined to the first portion 12 and releasably secured to the first portion 12 with the locking mechanisms 32, 132 so that the existing emergency escape slide 201 is disposed between the first portion 12 and the second portion 14. Thereafter, the container 10 may be transported to a storage location with a forklift or other transportation device.

Turning to FIG. 12, an alternative example is provided. In this example, the first portion 12 and the second portion 14 each include any number of alignment mechanisms 310, 312. In this example, the alignment mechanism is in the form of a visual marker (e.g., an arrow) to assist with properly positioning the first and second portions 12, 14 relative to the emergency escape slide storage location 204. Further, in this example, the egress door 206 may include any number of alignment mechanisms 311. A user may align the alignment mechanisms 310, 312 positioned on the container 12, 14 with the alignment mechanism 311 positioned on the egress door 206 to assist with properly positioning the containers 12, 14 relative to the emergency escape slide storage location 204.
